ROTATION PROCESSING MACHINE

摘要

A rotation processing machine includes a rotating device supporting a cylindrical workpiece via a rotation support jig; a processing device on which a cutting tool is mounted; and a turning loader that has grippers arranged about a turning central axis and that turns so that the grippers sequentially face the rotating device. The grippers are configured to individually move up and down, and a height position of each gripper is settable to a first height position where the gripper delivers and receives the cylindrical workpiece to and from the rotating device, and a second height position where the gripper delivers and receives the rotation support jig to and from the rotating device. The turning loader turns each of the grippers between an external delivery/reception position where the gripper faces an external transfer stand and an internal delivery/reception position where the gripper faces the rotating device, and is configured to set the gripper to the first or second height position at one of the external delivery/reception position and the internal delivery/reception position, and to turn the gripper to the other delivery/reception position while holding the gripper at the set height position.
